4 side effects of taking excessive vitamin B12 supplements
Many people take vitamin B12 supplements on their own or as prescribed by their doctors. This is because a substantial number of people do not get enough vitamin B12 from their food. Vitamin B12 is an essential vitamin that helps maintain the proper cell metabolism process and rate. However, its excessive intake can cause extra deposition of the vitamin in the body, resulting in associated side effects like the ones mentioned below. Digestive issues Overconsumption of vitamin B12 supplements can result in gastrointestinal problems. When the body has an excess amount of the supplement, it can lead to digestive distress. Symptoms can include mild diarrhea, nausea, and indigestion. Individuals who already have gastrointestinal problems or who are older are at a higher risk of developing this side effect. Insomnia Excessive consumption of vitamin B12 can worsen insomnia in individuals who already suffer from the condition. When the vitamin levels in the body cross the required amount, it can interfere with the person’s normal sleep cycle. Molecules of vitamin B12 act as an energy booster in the blood.
